Abstract
The utility model relates to a mine car wheel, which comprises an inner wheel body and is characterized in that the inner wheel body is sleeved with an outer rim provided with a rim and a tread. The utility model solves the following problems: the prior mine car wheel is made of cast steel and has the defects of multiple sand holes, pores and entrapped slag; the steel grade is unstable, the organizational structure is uneven, and the hardness of the tread is unqualified; the phenomena that the wheel cracks and fractures and the surface is easy to wear occurs frequently, and the running safety of a mine car is influenced badly; and the solid-forging is inapplicable as the lot quantity is small and the cost of a die is high, though the quality can be good due to the solid-forging of the wheel.
Description
Technical field
The utility model relates to a kind of tramcar wheel.
Background technology:
Tramcar wheel adopts steel casting at present, and its defective is: sand holes, pore and slag inclusion are many.The grade of steel instability, organizational structure is inhomogeneous, and tread hardness is not up to standard, and it is broken the wheel cracking often to occur, surperficial phenomenon easy to wear.Had a strong impact on the safe in operation of vehicle.Wheel is as adopting solid forging, and quality is good, but because of little in batches, the die cost costliness should not adopt.
Summary of the invention:
Goal of the invention of the present utility model provides that a kind of wheel is not easy to crack, the tramcar wheel of long service life and low cost of manufacture.
The purpose of this utility model is realized by following mode:
Tramcar wheel comprises interior wheel body, it is characterized in that: the outer rim that is with a belt wheel edge and tread on interior wheel body.
The beneficial effects of the utility model are: adopt built-up wheel, can upgrade outer rim again after the wheel thread damages, make manufacturing cost save half, and existing Casting Parts changed into use the forging rolling overcoat, can increase the service life 4-5 times like this.
Description of drawings:
Fig. 1 is the cutaway view of the utility model wheel.
The specific embodiment:
A kind of tramcar wheel, wheel body 1 in comprising is characterized in that: the outer rim 2 that is with a belt wheel edge 8 and tread 7 on interior wheel body 1.
Side at the inside face of outer rim 2 is provided with positive stop lug boss 3.
The outside face 4 of interior wheel body 1 and the both side surface of the web 5 between the axis hole 6 are the smooth surface of indent, and the elevation profile of interior wheel body 1 is a symmetry with the center shaft of axis hole 6.
Both side surface one side of web 5 is a helical, and opposite side is a cochlea shape.
Adopt web of the present utility model, promptly increased the intensity and the buffering ability of wheel, in the service life of also having improved axletree, interior wheel 1 and outer ring 2 usefulness interference modes are fitted in together, in order to make the combination of overcoat and interior wheel more firm, can reinforcement of weld at the opposite side that interior wheel body is relative with positive stop lug boss.
Claims (4)
